7 Application filed July 26,

To all whom it may concern:

Be it known that L'HANUEL Bnnros Y LAvnum, a subject of the King ofSpain, residing at No. 22 Gallo Street, S antiago, Cuba, have invented anew and useful Shutter Applicable toill Kinds of Folding Doors, of whichthe following is a specificathat the shutter is rolled up on being takenoff, and without the disadvantage, as ithappens'with the shutters now.in use, thatbeing' of a separable body, they have to be placed asideafter they have been used, an

7 operation which is quite troublesome.

7 and the bushing been folded.

Otheradvantages andpurposes of the invention will be understood 1n thecourse of this description, the illustrative drawings of 7 whichrepresent "Fig. l is a general view of the door show ing the shutter ina halt closed position.

Fig. 2 is a view of the shutter already rolled on its reel and of thedoor in position to be folded after the tracks, their annexes, guide andsafety bar have Fig. ,3 is a view of the shutter closed'at its outerface.

In the drawings, 2 indicates a shutter the constitution ofwhich is theointe d or rolled system which is the subject matter ofmv' applicationof the 26th of July, 1920. Serial No. 399.157,1 as this system ispreferably used in this case. The shutter 2' is rolled up at its iipperpart on the reel l plziC'ed 7 between the tu' o drums 15. These drumsare formedby the hollow cylinders 19 intheir interior 1'8, as'showninFig; 5, and rotate around the axlebox 32 Whichfits in the axle 3' of the.door 20. The drums 15 complete a one piece casting or stamped iron, the

Theaxle box 82 is secured to the nut-'37 screw threaded at itsend. I I

As arrangements substantially the same as those of ordinary doors, Ihere illustrate the drums of the door '16, the supporting means 14 ofthe axle of the door and through '17, the-tracks of that door.

The shutter is limited to the section inv starting from line 25. V r in13, are shownbraces which are rolled up in the reel, 15, from whichbraces hang dicated in 2 which covers the door-hole l, 7

the shutterwhich is also rolled in saidreel, as shown at 1, Fig. 2. Atthe doorsilland l overits threshold is arranged the guiding bar 10,supported by bracket 11. Y M

This bar is provided at 9wvith aset of uni versal joints from Which areconnected the, U-shaped section tracks 6 situated in an in verseposition, as indicated in 8.- Of the U track which has the larger flange26,

. engaging the edge of the door-hole 4: Which must cover the shutter 20like a frame, While the other adjacent U, 27,:serves as a guide for theshutter. h

hole and at that plate in 38 arej'ointed the strengthening or safetybars '5, the'joint of which only permits the side rotatio'nk or,movement of said bars. These bars are placed parallel to'the tracks'fiand are trans- "verselv secured to the latterby meansof the latches '7,and are rigidly maintained clamped to the door by means of the pins 8and enter by a strong frictionunder the bridges 3 at the height ol' thetop piece of the shutter,

At 12 are indicated somepieces to support the tracks and safety bars onbeing folded. The operation necessarv to open and close thisshutter israpid and simple,

Once they are rollednp in the position shownin Fig. 2,-th'at' is to say,when'the door is in the lovver'pos tion, 1t W llbe sufiicle'nt to takeout tracks 6,' causing the same to rotate on the setbfjoints 9,'andinsert r ing-them through U 26 in the edges of the r hole 4.; .thenthestra bars5 are raisedandr arranged around the joint 38fand saidbars aresecured and are passed under the bridges 3 and the latches and clamps 7and 8 are properly adjusted. Then the shutter 2 hanging from the foldingbraces 1.3 is pulled and slides until it is placed between the tracks27.

\Vhenever it is desired to raise the shutter, said shutter is pushedupwards, said impulse being accompanied by a hook or a similar device,and as'soon as it is rolled up the latches and clamps are disconnectedfrom the safety bars and the tracks, the former sliding out the bridges3 and rotating laterally; then the frame tracks are taken out of theedges of the door-hole and rotate in a facing position around theuniversal joint set 9, carrying along with its, the plate 31 whichcarries the bars 5, folding both the tracks and bars in the positionindicated in Fig. 2.

It is evident that slight modifications can be made in everything thathas been set forth, provided no alteration is made in the fundamentalobject of the invention, as stated below WhatI claim is 1. In flexibledoors, the combination of a large flexible door having an openingtherein, and a flexible door slidably engaged in said opening.

2. In flexible doors, the combination of a large flexible door having anopening therein, guides at said opening, and a door slidably engaged insaid guides, said guides being removable from said opening to allow saidlarge door to be flexed when raised.
